From Youth Today:

Research has shown that adolescent parenthood is far more common among young people in foster care than among their peers in the general population. Potential explanations for the high rate of parenthood among youth in foster care include a desire to create a family and fill an emotional void, a perceived lack of stigma or opportunity costs, the developmental effects of childhood trauma, a lack of information about sexual and reproductive health, difficulty accessing sexual and reproductive health care services, and the absence of close relationships with parents or other trusted adults.

The high rate of adolescent parenthood among youth in foster care is disconcerting for several reasons. First, being an adolescent parent is difficult under the best of circumstances. It is even more difficult when the adolescent parent is a young person in foster care with a history of abuse, neglect or other trauma, whose living arrangements are unstable and who lacks family support. Second, youth in foster care are already at risk for poor outcomes; becoming a young parent could increase that risk. Third, the children of adolescent parents in foster care are at higher risk for child abuse and neglect and have a higher rate of child welfare services involvement than the children of adolescent parents not in foster care.
